Although Yerli is confident that Crysis will run on older setups, he suggests that if you can only play the game on DX9, try not to view the game running in the superior DX10. "We work hard to give everyone a great experience," he states. "You should not miss anything when [only] playing it on DX9, but if you get a chance to play it on DX10 you might [miss the fidelity when going back to DX9].

He adds that close ties with software and hardware partners have helped Crytek overcome the complicated transition to Vista, DX10 and multi-core processors. Yerli says, "Working with early DX10 hardware was challenging, but our strong connections with Nvidia, Intel and Microsoft have helped a lot. We rarely had crashes, blue screens or rebooting machines."
